Whats behind the glove box?

want to try putting my head unit inside of my glove box by making a bracket, and cutting a little behind the glove box backing so that when I have my doors off, it will look as if I dont have a radio to those "looking".... however, is there anything behind the glove box that will nto allow me to cut it out and mount my radio? I figured I would ask on here before actually going through and taking it all apart. Also, how much room is there behind it? I was thinking of also mounting an older style playstation in there below the radio if possible Thanks
